convert GPS latitude longitude to Cartesian X and Y

Question

I found many algorithms to convert (latitude, longitude) into (X, Y)... however, I cannot verify if the results I'm getting are correct.. I found also this link which does the conversion online.. but I couldn't manage to get any algorithm which gives the same results as the one given by the link..

I would be grateful if anyone has encountered the same problem and can help me
